Rear bumper for an automobile



FIG. 1 is a front elevational view of a rear bumper for an automobile in accordance with my new design;

FIG. 2 is a top plan view thereof;

FIG. 3 is a bottom plan view thereof;

FIG. 4 is a left side elevational view thereof;

FIG. 5 is a right side elevational view thereof;

FIG. 6 is a bottom, front and left side perspective view thereof; and,

FIG. 7 is a top, front and right side perspective view thereof.

The rear view of the rear bumper for an automobile forms no part of the claimed design. The inside surfaces of the rear bumper for an automobile, shown in broken lines in FIGS. 2, 3, 6 and 7, form no part of the claimed design since the inside surfaces are hidden when the rear bumper for an automobile is mounted to the automobile. 

CLAIM The ornamental design for a rear bumper for an automobile, as shown and described.
